EXHAUST-IVIUFFLEFI.`

SPECIFICATION forming part of Letters Patent No. 758,402, dated April 26, 1904.

Application tiled November '7, 1903. Serial No. 180,225. (No model.)

'a citizen of the United States, residing at J unius, in the county of Seneca, State of New York, have Invented certain new and useful Improvements in Exhaust-Mufflers; and I dor hereby declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same.

This invention relates to mufflers, such as are employed in connection with the exhaustpipe of high-pressure engines, and particularly gas-engines, the object of the invention being to provide a muffler which will reduce the noise of the exhaust to aminimum, which will be simple in construction and most eiiicient in its operation.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in both views, Figure l is a side elevation showing a mufiier embodying' the presentA invention. Fig. 2 is a longitudinal section taken vertically through the muffler.

Referring now to the drawings, the present muffler' comprises an upper chamber 5 and a lower chamber 6, both of which are substantially cylindrical-shaped in their main body portions and have conical end portions, as illustrated.

The two chambers or members 5 and 6 are rigidly connected by means of the straps or braces 8 and 9, and midway of the ends of these two members there is a connecting-pipe 10, the passage of which is controlled by means of an ordinary valve 11.

The upper member 5 is designed as a reservoir to hold water and is provided with a filling-opening 12, having a cap 13, provided with a vent 14:, which permits of ingress of a small quantity of air as the water passes from the reservoir through the connecting-pipe to the lower chamber or member.

In the lower member at the base of one conical end is a transverse foraminous partition 15, between which and the opposite end of the member is a filling 16, of absorbent materialsuch as mineral wool, sponge, or similar subat its base, said exhaust-pipe extending axially of the lower member and 'terminating slightly short of the middle point thereof, the extremity of this exhaust-pipe being buried in the absorbent material, as illustrated. The conical end of the lower member through which the exhaustpipe extends is perforated, as illustrated, so that the exhaust after being discharged in the direction of the opposite end of the lower member will pass radially in the direction of the wall of said member and then rearwardly and out through the perforations.

In practice modifications of the specific construction shown may be made and any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.

What is claimed isv A muffler comprising upper and lower chambers having a valved connecting-pipe communicating with the lower chamber through its upper portion, said upper chamber being adapted to hold a liquid, the lower chamber having perforations through one end and having a transverse foraminous partition adjacent to said perforated end, an exhaust-pipe passed through the perforated end of the lower chamber and through the partition and a filling of absorbent material between the partition and the opposite end of the chamber and surrounding the exhaust-pipe.

In testimony whereof I afx my signature in presence of two witnesses.
